can any one help me
Quote:
void Mac802_11::add_hidden_node(int noeud)
{
if(noeud==index_){printf("\n\n******************************\n\n");
goto il_existe;
}
printf("========%d=====add===> %d\n",index_,noeud);
struct table_n_cach *temp;
struct table_n_cach *table;
if(table==NULL) {
table = (struct table_n_cach*)malloc(sizeof(struct table_n_cach));
table->val = noeud;
table->next = NULL;
goto il_existe;}
